DevTools previously called in several places with user-defined values. This could lead to runtime errors if those values had an overriden attribute. This commit replaces those callse with instead.
New test cases have been added.
* Improved inspected element props with inline previews
This mimics the inline preview shown by the brower console and dramatically improves the UX when inspecting deep values. I also updated tests to add more coverage for this new functionality.
* Cleaned up the DataView vs typed array check
* Added early bailouts to DevTools when generating preview strings for iterables/objects/arrays, to avoid doing unnecessary work
